Title: Cold rolling method for stainless steel strip in sendzimir rolling mill
Inventor: IZUMI YASUO
IPC: B21B27/00
Filed: 1980-12-24
Abstract: PURPOSE: To make the prevention of the breakdown of a steel strip possible by using the 2nd intermediate driving rolls of roughened initial surface roughness in cold rolling of a stainless steel strip with 20-stage Sendzimir rolling mills.  
     CONSTITUTION: In cold rolling of a stainless steel strip S with 20-stage Sendzimir rolling mills, the initial surface roughness of the 2nd intermediate driving rolls 3 is set ≥0.8μ (Ra) up to 1.6μ (Ra). If the roughness of the rolls 3 is increased in this way, the generation of slips between said rolls and the 1st intermediate driving rolls 2 is obviated and the breakdown of the strip S is prevented. Hence, the possibility of damaging work rolls 1, the rolls 2, the rolls 3, the 2nd intermediate idler rolls 4, and backing bearings 5 in accordance with the breakdown of the steel strip is eliminated and this is helpful for improvement in productivity.

Filed: 1994-08-05
Abstract: PURPOSE:To fully charge a battery without fail by eliminating fluctuation of the battery voltage due to variation of the contact resistance between a battery terminal and a charging contact, thereby preventing a premature charging caused by fluctuation of the battery voltage. CONSTITUTION:When a battery 5 is loaded to a charger, the + side battery terminal 6 is connected simultaneously with charging contacts 3a, 3b while the - side battery terminal 7 is connected with a charging contact 3c. Under that state, first and second charging currents 2I and I are fed from the first and second terminals T1, T2 at a charging power supply section 2 to the battery 5 thus starting the charging operation for the battery 5. Voltage of the battery 5 increases as the charging operation proceeds while eliminating the fluctuation caused by variation in the contact resistance between the battery terminals 6, 7 and the charging contacts 3a, 3b, 3c. This constitution prevents premature charging due to fluctuation of battery voltage and full charges the battery 5 surely.

Abstract: PURPOSE:To increase the reliability of end point detection, and improve yield by converting the time variation of the image of plasma light to the distance variation on an image processing apparatus, and measuring plasma temperature by applying Boltzmann's formula to the intensity ratio of two specified wavelengths concerning the image of plasma light. CONSTITUTION:The images of plasma light generated by a plasma generating apparatus 1 passing an observation window 15, are converged by condenser lenses 3a, 3b, and enter monochrometers 4a and 4b, respectively, thereby obtaining images of plasma light having a specified wavelength. The optical paths of the two images of plasma light are converted by 90 deg., by a mirror 90 deg.-converter 5, and vertical images 16 of plasma light are converted into horizontal images. The sizes of horizontal images of plasma light are controlled by lenses 6a, 6b, and the images enter a hexagonal rotary mirror 7. Since the mirror 7 rotates with a constant number of revolutions, the temporal variation of the image of plasma light is displayed as the spatial variation on the surface of a film 18 arranged in an image processing apparatus 8. In this case, based on characteristics of two specified wavelengths concerning the image of plasma light, the temporal variation of plasma temperature can be obtained by applying Boltzmann's formula.

Title: Controller for air conditioner
Inventor: TOKURA SATOSHI
IPC: F24F11/02
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To solve a conventional problem that control of suction temperature based on the delivery temperature is difficult if the delivery temperature and the suction temperature are not interlocked perfectly and the heat carrier circulation quantity and the indoor air volume are low when the opening of an expansion valve is regulated using the delivery temperature in order to control the suction temperature to some reference temperature and thereby dews on the surface of an indoor heat exchanger are frozen. SOLUTION: In the inventive air conditioner, suction temperature (K) can be controlled precisely and stably by monitoring it directly and regulating the opening of an expansion vale or the reference delivery temperature such that the suction temperature (K) is sustained in a stable region. When the suction temperature (K) drops abruptly, it is raised quickly by increasing the opening of the expansion valve or opening it frequently thus protecting the indoor heat exchanger against freeze.

Title: Rush current preventing circuit
Inventor: YAMAMOTO MASAYUKI
IPC: G05F1/10
Filed: 1983-10-05
Abstract: PURPOSE:To limit rush current at the instantaneous interruption of power supply or the like surely and to monitor normality/abnormality of a switching circuit easily by detecting the voltage of current limiting resistor by a voltage detecting circuit and loading/unloading the resistor. CONSTITUTION:When a power supply PS is instantaneously interrupted, an input voltage detecting circuit 24 detects the interruption and sends a signal Sa to a resistor both-end voltage detecting circuit 22 to open a switch S. When the power supply is turned on, rush current is limited by power supply limiting resistors 14, 16 and when the rush current is suppressed and the voltage applied to both the ends of the resistor is dropped lower than a prescribed value, the circuit 24 closes the switch S to turn on normal operating state. If an opening/ closing control circuit of the switch S is defective, the switch S is not closed in spite of the removal of the rush current and the resistor 14 is kept at connected state as it is. In this case, a signal Sb is sent to a switch abnormal moment protecting circuit 26 to open a breaker 10. If the input voltage is abnormal as the result of monitoring, the circuit 24 sends a signal Sc to open the breaker 10.
